Squadron vehicles are special vehicles obtainable by squadron research points or by golden eagles. Squadron research points are gained from being active while being in a squadron. The earning rate is one squadron point for every 200 research points earned, which are given every two days. Maximum earnings are 360 points every 3 days. Squadron vehicles, as mentioned above, can also be bought for golden eagles. These vehicles often have something special about them, such as the M901's missile launcher or the Firecrest's torpedo.
